“…At c R = 1, the model over-predicts β I by almost a factor of two. However, at c R = 0.55, the model is consistent with the measured values, and the general trend is consistent with similar data from other groups [4,5]. Figure 3 shows the measured α I and β I for the same device, but as a function of the current at two constant bias points, 20% R n (blue circles) and 30% R n (green triangles).…”

“…An empirical form for R(I, T ) was proposed by Cabrera [2]. Also, predictions based on a Ginzburg-Landau theory for the relationship between the logarithmic partial derivative of resistance with respect to temperature, α, and current, β, have been proposed [3] and compared with data [4,5]. Although these models predict some features of the data, they do not predict the general dependence of β on the bias point, R(I, T )/R n , in the transition or as a function of the current at a constant bias point.…”

Superconducting microcalorimeters based on transition-edge sensors (TESs) are being successfully used in applications ranging from optical photon counting to gamma-ray and alpha particle spectroscopy. Practical instruments often require a complex optimization among speed, linearity and energy resolution. However, a lack of understanding of the superconducting transition limits our ability to predict the behavior of a new TES design. Specifically, there is an unmet need for a model that predicts the current and temperature dependent resistance surface that describes the transition: R(I, T ). This paper describes the predictions of a two-fluid model for the resistance of a TES based on a Ginzburg-Landau form of the critical current. We compare the predictions of the model for the logarithmic derivatives of resistance with temperature and current (α and β) to measurements of TESs used in x-ray and gamma spectrometers. The model shows excellent qualitative agreement that provides useful insight into the dependence of α and β on the current density and bias point of the TES.

Sterile neutrinos, coherent scattering, and oscillometry measurements with low-temperature bolometers

Coherent neutrino-nucleon scattering offers a unique approach in the search for physics beyond the Standard Model. When used in conjunction with mono-energetic neutrino sources, the technique can be sensitive to the existence of light sterile neutrinos. The ability to utilize such reactions has been limited in the past due to the extremely low energy threshold (10−50 eV) needed for detection. In this paper, we discuss an optimization of cryogenic solid state bolometers that enables reaching extremely low kinetic energy thresholds. We investigate the sensitivity of an array of such detectors to neutrino oscillations to sterile states. A recent analysis of available reactor data appears to favor the existence of such such a sterile neutrino with a mass splitting of |∆m sterile | 2 ≥ 1.5 eV 2 and mixing strength of sin 2 2θ sterile = 0.17 ± 0.08 at 95% C.L. An array of such low-threshold detectors would be able to make a definitive statement as to the validity of the interpretation.
